The mailing list for listmasters using Sympa

[Jose-Marcio Martins da Cruz <address@concealed>]

Hi,

A common reason for Google refuse all messages from one domain is wild 
forwarding.

E.g., if some of your students use gmail to manage their email, and they forward to google all 
messages from their sabanciuniv.edu email accounts without any previous filtering, you'll just find 
your mailserver sending spams to google. After some amount of spam, google just blacklists your 
mailserver for some time.

Well, this is a possible cause. There may be others. And these reasons may not be related to your 
list server.

So, before trying to tweak sympa to not send these normal warnings, you should try to identify what 
kind of messages are being considered as spam by google, and act there.

My 2 cents.
